      Re: Form S-3 Registration Statement

Ladies and Gentlemen:

      We have  acted  as  counsel  for  American  Bio  Medica  Corporation  (the
"Company") in connection with the registration  statement of the Company on Form
S-3 (the "Registration Statement") filed on the sate hereof under the Securities
Act of 1933, as amended (the  "Securities  Act") covering  400,000 common shares
("Shares"), par value $0.01 per share, of the Company, issuable upon exercise of
certain common stock purchase  warrants  ("Warrants")  to be offered and sold by
the selling shareholders named in connection with the Registration Statement.

      We have examined  originals or copies,  certified or otherwise of all such
records  of  the  Company  and  all  such  agreements,  certificates  of  public
officials,  certificates of officers or other representatives of the Company, as
we have deemed  necessary and appropriate as the basis for our opinion.  We have
also reviewed such questions of law, as we have deemed necessary and appropriate
for the purposes of rendering the opinion set forth below.

      In  rendering  our  opinion,  we  have  assumed  the  authenticity  of all
documents  submitted to us, the genuineness of all signatures and the conformity
to authentic  originals of all documents submitted to us as copies. We have also
assumed  the legal  capacity  for all  purposes  relevant  hereto of all natural
person and with respect to all parties to  agreements  or  instruments  relevant
hereto  other  than  Company,  that such  parties  had the  requisite  power and
authority  (corporate or otherwise),  to execute and deliver such  agreements or
instruments  and that such  agreements  or  instruments  are valid,  binding and
enforceable obligations of such parties.

      Based on the  foregoing,  it is our  opinion  that the  Shares if and when
issued upon  exercise of the Warrants  pursuant to the terms of the Warrants and
when the consideration  therefore has been received by the Company,  such Shares
will be legally issued, fully-paid and nonassessable.

      Our opinion expressed above is limited solely to the Business  Corporation
Law of the State of New York, and we express no opinion as to any other laws.

      We hereby  consent  to the  filing of this  opinion  as an  exhibit to the
Registration  Statement and to being named as an expert in the Prospectus  filed
as part of the Registration  Statement.  This opinion may not be used, quoted or
relied upon for any other  purpose nor may this opinion be furnished  to, quoted
or relied upon by any other person or entity, for any purpose, without our prior
written consent.

                                   Very truly yours,

                                   TUCZINSKI, CAVALIER, BURSTEIN & COLLURA, P.C.
